To a/ZZ whom, t may concern.'

Beit known that I, GEORGE R. MOON, acitin zen of the United States, residing at Columbus, in the county of Franklinand State of Ohio, have invented a certain new and useful Improvement in Baking-Ovens, of which' the following' is a specification. v

My invention relates to an improvement in baking-ovens of that class which are adapted for use in conjunction with gasolene or gas stoves or burners, and has particular relation to the improvement of the construction set forth in myformer patent, No. 598,570, issued under date of February 8, 1898. The objects of my-present invention are to provide a baking-oven of the class mentioned with improved means for equalizing the circulationof heat through the various portions of the oven, to provide in conjunction therewith an improved heat-deflector, and to produce other improvements the details of construction of which will be more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawings, in which- Figure 1 is a front View of my improved baki'ng-oven. Fig. 2 is a sectional View on line a a; of Fig. 1. Fig. 3 is a sectional View taken through the oven at right angles with that shown in Fig. 2. Fig. 4 is a sectional view on line y y of Fig. 1, and Fig. 5 is a View in elevation of a portion of one end of the oven-body.

Similar numerals refer to similar parts ythroughout the several views.v

In carrying out my invention I employ, as set forth in my said former patent, an exterior casing l, having suitable openings 1a in its upper side, within which is arranged a casing 2. This innercasing does not extend across the bottom of the oven-body and is omitted from that portion of the frontof said body in which is formed a doorway 3. This doorway is adapted to be closed by one or more doors 4, the latter being preferably of double thickness, as shown. 5 represents a heat receiving and deilecting body which is supported in the lower portion of the ovenbody and extends between opposite sides thereof. This deilector, as indicated in the drawings, is in the form of a transverselyarranged triangular box, between the forwardjvertical wall of which and the forward inner-casing wall is formed a vertical line 6.

The rear and smaller end of the defiector 5 terminates at a point at a desirable distance.

the drawings, the verticall plates l0 are so.

arranged with relation to each other as to form between them and between the rearmost plate 10 and the rear verticallwall of the inner casing vertical flues, such as are indicated at 11 and 12. The inner plate l0, as shown in the drawings, is so arranged with reference to the rear end of the deflector 5 as to leave a heat outlet or opening l0 between the lower 4end of said inner plate and said deector, this opening being of slightly-less size than the flue-opening 11. which thus lead, respectively, from the lower portion of the oven-body'to the open spaces above the shelves 9, are, as shown more clearly in Fig. 2 of the drawings, graduated in sizethat is, the inner and shorter ilue 11 is of smaller size than the outer flue 12.

The vertical flue plates or walls 7 are, as indicated in Figs. 3 and 4 ofthe drawings, provided with perforations 13, through which communication with the open spaces above the shelves and above the triangular-deflector 5 is established with the central iiue 8.

At opposite points in the side or end walls of the inner casing I provide the desired number of openings 14, said openings forming a communication between the interior of the inner casing and the dues 15, which are formedbetweeu said inner and outer casings. In each end o f the inner casing I form an opening 14, which leads into the interior of the defiector, and in the ends of the exterior casing I form similar openings 14h.

Between the end or side walls of the inner Within the interior ofv These ilues,

IOO

and outer casings 1 and 2 I provide, asindicated in section in Fig. 3 of the drawings and in dotted lines in Fig. 2, U or yoke shaped partitionsl, the latter inclosing, re-

In utilizing my invention the oven-body' formed as above described is adapted to be seated over the burners of a gasolene or gas stove or other suitable heat-generating apparatus. into contact with the rearwardly and upwardly inclined Linder side of the deflector 5, the greater portion of the heat thus discharged following the incline of said deector and passing upward through the flues 11 and 12 and through the opening 10a, thus being distributed into the oven-spaces which are below and above the shelves. In order that the greater quantity of heat will not be carried int-o the lower oven-spaces, I have graduated the size of the opening 10iL and dues 11 and l2 for the purpose of equalizing the distribution of heat through said opening and flues. It will readily be seen that this graduation is made necessary by the natural tendency of the heatto rise through the first openings or fines encounteredafter leaving the deiector. Through the construction described it is obvious that the heat will be equally distributed Within the oven-spaces and that the openings 13 in the central lluewalls will afford a means of communication between the flue 8 and said oven-spaces. From each of these oven-spaces the heat may pass through the openings 14 into the lines 15 and out through the openings 1a in the top of the outer casing. The forward vertical The heat which rises therefrom comes flue 6 also affords a means of communication between the lower portion of the oven-body and the baking-spaces, thus providing, in conjunction with the opening l0 and 'lues 11 and 12, a complete circulation of heat over the shelves.

Owing to th'e employment of the deiiector, end openings 14E, and the outer-casing openings 14th, it will be seen that air from the outside of the oven-body may enter the deiiector and becoming heated therein will pass upward through the due 8 and thence into the oven-spaces, thus supplying the latter with an additional Volume of hot air.

Having now fully described my invention, what I claim, and desire 4to secure by Letters Patent, is-

In an oven, the combination with a doublewalled casing having a doorway therein and doors therefor and a triangular delector-casing supportedin the lower portion of the oven- 4body, of parallel shelves arranged one above the other above said deflector, plates 10 extending downward from the rear ends of said shelves, said plates being so arranged with relation to each other to the rear wall of the inner casing and to the rear end of the deiiector as to provide an opening between the lower portion of the oven-body and the space below the lowershelf and dues leading respectively to the spaces above the shelves, said opening and lines being graduated in size as described,central oven partition-plates 7 having perforations therein and forming a central fine S, the external casing being provided with outlet-openings 1it and the internal 'casing provided with openings 14, substantially as specified.
